No revenue estimate for XBOX — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $83.7M — a different platform, not this one.
Portal 2
Also onSteam
The highly anticipated sequel to 2007's Game of the Year, Portal 2 is a hilariously mind-bending adventure that challenges you to use wits over weaponry in a funhouse of diabolical science. Using a highly experimental portal device, you’ll once again face off against a lethally inventive, power-mad A.I. named GLaDOS. Break the laws of spatial physics in ways you never thought possible, with a wider variety of portal puzzles and an expansive story that spans a single player and co-op game mode.
